Computer World: Apple on Tuesday made it clear that it will no longer patch OS X 10.6, aka Snow Leopard, when it again declined to offer a security update for the four-and-a-half-year-old operating system.

As Apple issued an update for Mavericks, or OS X 10.9, as well as for its two predecessors, Mountain Lion (10.8) and Lion (10.7), Apple had nothing for Snow Leopard or its owners yesterday.
